Stuck in recovery mode and ADB says unauthorized.

Hi There
I started using my TF101.
I had a custom rom on it and I choose for reset to factory settings.
the next time I booted my TF101 it went directly into clockwork recovery. (one click and I am in the recovery mode v 3.1.0.1)
First I tried to flash an older custom rom. This had no effect.

Then I wanted to cold boot my TF101.
When I choose for the cold boot option it doesn't boot. The tablet is active but it doesnt boot.

Once you gave a custom recovery installed never ever use anything else to do any kind of wiping! That got you into this mess...
You can't use adb in recovery probably because that CWM version does not support it and you can't use it in Android because you probably have USB debugging disabled. Can't change that if you can't boot, so I think your best bet is to use Easy Flasher to return to stock.
From there you can start again from scratch.
Find the thread for Easy Flasher on XDA and check out Frederuco's guide in the Development section on this forum.
Good luck!

Thank you very much.
So you think that there is a solution. I thougt I bricked it.

I installed the naked drivers and later on the nvflash windows driver.
When I boot the tf101 with the power en vol-up button held my Win pc sees the tablet.
(when I installed the nvflash driver the device manager says nvidia usb boot ....)

When I use the easyflasher the program says done but nothing happened.
I tried the sdk1 and sdk2.

then I used nvflash.
i run the download.bat.

the following text appears and for the first time something happened on my tablet. (I see white letters in the topcorner.)

When I now boot my tf101 there are three options.
1. just the power on button - > screen with asus logo. (different logo then before)
2. vol up and power -> apx mode - my windows pc sees the tablet (as nvidia...)
3. vol down and power - > I can only choose wipe data. (no android anymore)

Where did you get nvflash from? I have not used EasyFlasher since I don't have a 101 but I don't see an option to just run nvflash.. Did you get that somewhere else??
But anyway, the output looks good and it could well be that you do not see an Android anymore because you don't have anything on the system partition. Or you flashed the wrong bootloader - I have no idea and your description is not detailed enough to even guess...
You downloaded the Asus firmware from their website, put that zip in to the asusupdate folder in Easy Flasher and flashed it?

Actually yes, looking at the nvflash output, it recreated and formatted each single partition. And since you did not flash anything to them, there can't be a recovery or system. Everything is squeaky clean and empty
Try to flash the stock rom again

You can also try to flash the TWRP recovery that is offered in EasyFlasher. It is hopelessly outdated but the point is to get any recovery onto the tablet. Once you got that you can easily update it.
Keep us posted

Got it from xda developers forum.

i used easyflasher again.
choose the top option. flash recovery.
I choose the second option . twrp 2.2.1.
it said it was succesfull

then i booted.
the tf101 went into recovery. :-)
but it was CWM-based recovery v 5.5.0.4 roach-tf101-r2 (very strange but I am in recovery)

then i formatted a microsd in fat32.
I put a older HD revolution rom on it and booted again and went into recovery.

i choose install zip from sdcard.
now i choose the first two options
it looks that my tf101 doesnot see the mircosd anymore
could this be the case?

in the left corner of the screen it cwm recovery says:
--installing /sdcard/update.zip
finding update package...
opening update package...
E:can't open /sdcard/update.zip
(no such file or directory)

/sdcard is your internal storage and the recovery is looking for a file named "update.zip".
That was how we flashed back in the stone age or a little later
Do you have another option in that recovery?
Post a screen shot of the recovery options if you can.
In the meantime you can download the latest TWRP recovery from here: https://forum.xda-developers.com/sho....php?t=2434422
It comes in a flashable zip file which you can flash in your current recovery.
Best would be if we could get a better recovery onto the tab... I never liked CWM...
You may have to rename the TWRP zip you downloaded to "update.zip" to get your Rogue recovery to flash it - idk....
If you can't get your recovery to see external storage, you may have to adb push the file you want to flash to /sdcard.
Check if you have an adb connection when booted into recovery with the command:
adb devices
